Brian Birdwell - 9/11 Pentagon survivor ( 00:13:36 )

One minute he was visiting the bathroom down the hall from his Pentagon office. The next minute he was burned over 60% of his body from an unknown explosion and resulting fires. That was the hell unleashed on Lt. Col. Brian Birdwell on 9/11/2001. He didn't yet know that a 757 passenger jet had been hijacked by terrorists and flown into his side of the building. Nor that he was one of the few survivors from his office sector of the Pentagon. Or the levels of pain and agony associated with his resulting recovery. That was all to come.
